scoow: since you made many of the same points I did at about the same time, let me respond to a couple of yours:
- Yes, I read the guidelines to say that a person has to nominate him or herself. This makes sense to me since there are certain obligations that one takes on in becoming an ambassador, such as making ones self available to answer questions via PM and/or email. Some folks may be the sorts of angels that cblaisd describes on forums but have no interest in doing so in a more formal capacity or in offering themselves up to do the same via PM or email. So the person should be the one to nominate themselves for this honor/obligation.
- I think the idea of a poster being an ambassador for one forum only (and also not also being a TB member and/or moderator) is to spread around the opportunities to be serve FT. Besides, as the guidelines point out, mods and TB members are supposed to be angels anyway!
- As I see it, some forums could have tens of ambassadors and some may have none. Frankly, some forums NEED tens of ambassadors and some need none.
